Wimbledon champion Serena Williams has been romantically linked with rapper Drake.

According to the Sun, the two were spotted kissing after Williams' victory against former world number one Victoria Azarenka in the Wimbledon quarter-final match.

"Publicly she says they're just friends but Drake has been by Serena's side throughout the tournament and when they've been away from the public and relaxed, it's been pretty obvious that they are together," a source said.

"Even Serena's team have been talking about it in the clubhouse to a few people they trust. She has been incredibly focused on her title bid.

"But if she's had a quiet moment she's spent it with Drake, even going to watch his Wireless set and having dinners in London," the insider added.

During a press conference after Williams defeated rival Maria Sharapova in the semi-finals, she was quizzed about the Canadian rapper's presence during the match.

"It's all about luck. You got to keep your luck around. We've been friends for like so many years, just like family. Kind of like we're on a streak right now. We got to do this," she said.

Meanwhile, Rihanna's former boyfriend shared a picture of Williams, lifting the trophy on Instagram.
